CARDING- Specification of Letters Patent.

MACHINE.

Patented Jan. 16, 1906.

To all whom it may concern.-

Be it known that I, J AMES J. RAE, a citizen of the United States, residing at Cherry Valley, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Carding-Ma chines, of which the following is a specification.

My invention relates toimprovements in carding-machines or machines for carding wool, cotton, &c., and more particularly to the Workers and strippers, so termed, combined with the main cylinder.

The object of my invention is to improve upon the construction of a carding-machine as now ordinarily made, and particularly the arrangement of the workers and strippers relatively to the main cylinder and their combination therewith.

In my improved construction of a carding-machine I combine with the main cylinder the worker-rolls, preferably ten in number, arranged in pairs around the main cylinder and each workerroll in engagement with the main cylinder, but none of the worker-rolls in engagement'with each other. I also combine with the main cylinder the stripper-rolls, preferably five in number, and each stripper-roll located between each pair of worker-rolls and in engagement with each of said worker-rolls and also in engagement with the main cylinder.

By means of my improvements the wool or other material to be carded passes from the main cylinder onto one worker-roll of a pair and from said worker-roll onto a stripper-roll and from the stripper-roll onto the main cylinder, and at the same time the material from the other worker-roll of a pair of worker-rolls located on the other side of the stripper-roll which has passed onto said worker-roll from the main cylinder also passes onto the stripper-roll, making two thicknesses of material on the stripper-roll to mix the material, and then both thicknesses of material pass onto the main cylinder, and this operation is repeated and takes place in connection with every worker-roll arplund the main cylinder and every stripperro per-rolls as there are worker-rolls, and each stripper-roll is located between and in engagement with a pair of worker-rolls.

Referring to the drawings, Figure 1 is a There is one-half the number of str1plicker-in roll 8 and to the tumbler roll 9 and from said roll 9 to the main cylinder 5. On the opposite side of the main cylinder '5 is what is termed a fancy roll 10 and a dolfer roll 11 on a shaft 12, mounted in bearings 13 on the frame 1.

All of the above-mentioned parts may be of the ordinary and well-known construction and operated in the usual way in cardingmachines.

I will now describe mv improvements.

Arranged around the main cylinder 5 are the rolls 14, termed workers, preferably ten in number and arranged in pairs, and each worker-roll is in engagement with the main cylinder 5; but none of the workerrolls are in engagement with each other. Also arranged around the main cylinder 5 are the smaller rolls 15, termec strippers, preferably five in number. Each stripper-roll 15 is located between a pair of worker-rolls 14 and is in engagement with each one of the pair and also in engagement with the main cylinder 5. The worker-rolls 14 are all rotated at a uniform speed in one direction opposite to the direction of rotation of the main cylinder, in this instance by means of a drivingbelt 16, passing around drivingrolls 17. The stripper-rolls 15 may be driven in any usual way in the same direction as the worker-rolls 14.

In Fig. 2 is shown how the material 7 passes from the main cylinder 5 onto each of a pair of worker-rolls 14 and from one of the worker-rolls 14 onto the stripper-roll 15 and also from the other Worker-roll 14 onto the stripper-roll 15 to make two thicknesses and mix the material, and then from the stripper-roll 15 the material passes onto the main cylinder 5. This operation is repeated, and the same operation takes place with each pair of worker-rolls and the stripperroll between them, so that there is double carding and double mixing and very satisfactory results are obtained.

It will be understood that the details of construction of my improvements may be varied, if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a carding-machine, the combination with the main cylinder, of the worker-rolls arranged in pairs, each one of a pair in engagement with the main cylinder, and the stripper-rolls, a stripper-roll for each pair of worker-rolls, and in engagement with each one of the pair, and also in engagement with the main cylinder, and means for rotating the workers and strippers in the same direction and opposite to the direction of rotation of the main cylinder, substantially as shown and described.

2. In a carding-machine, the combination with the main cylinder, of two worker-rolls in engagement therewith, and a stri per-roll in engagement with each of the wor er-rolls,

and also in engagement with the main cylin der, and means for rotating the workers and the strippers in the same direction and opposite to the direction of rotation of the main cylinder, substantially as shown and described.

3. In a carding-machine, the main cylinder, a worker-roll in engagement therewith and adapted to receive the material therefrom, a second worker-roll in engagement with the main cylinder, and adapted to receive the material therefrom, a stripper-roll in engagement with both worker-rolls, and adapted to receive the material therefrom, and also in engagement with the main cylinder, and adapted to transfer the material from both worker-rolls onto the main cylinder, and means for rotating the workers and strippers in the same direction and opposite to the direction of rotation of the main cylinder, substantially as shown and described.
